RESUMO

Ukraine surveillance data suggest high tuberculosis (TB) incidence, including multidrug resistance. Of 299 newcomers from Ukraine screened in San Francisco, California, USA, by using an interferon-γ-release-assay (IGRA) and chest radiograph, 7.4% were IGRA positive and 1 had laboratory-confirmed pansusceptible TB. Screening with IGRA and chest radiograph can help characterize TB risk.

RESUMO

INTRODUCTION: Sex work is a common phenomenon, but socially invisible and stigmatized. Due to exposure to work-related risks, sex workers (SWs) are vulnerable to developing health problems. However, little attention has been paid to their mental health. The purpose of this systematic review was to synthesize the existing literature on mental health and to explore risk factors related to psychopathology in sex workers. METHODS: A systematic review (CRD42021268990) was conducted on the Web of Science, PubMed, Scopus, and PsycInfo for peer reviewer papers published between 2010 and 2022. The Newcastle-Ottawa Scale (NOS) was used to examine the quality of the studies. Of the 527 studies identified, 30 met the inclusion criteria. RESULTS: Mental health problems were prevalent among sex workers. Depression was the most common mental health problem; however, other psychological problems were also high, including anxiety, substance abuse, and suicidal ideation. Sex workers are exposed to numerous work-related risks, including violence and high-risk sexual behaviors. Despite the high prevalence of mental health problems, SWs often encounter significant barriers to accessing healthcare services. CONCLUSION: These results suggest the need to focus on preventive measures to promote psychological well-being among sex workers.

RESUMO

Patients with fibrous dysplasia (FD) often present with craniofacial lesions that affect the trigeminal nerve system. Debilitating pain, headache, and migraine are frequently experienced by FD patients with poor prognosis, while some individuals with similar bone lesions are asymptomatic. The clinical and biological factors that contribute to the etiopathogenesis of pain in craniofacial FD are largely unknown. We present two adult females with comparable craniofacial FD lesion size and location, as measured by 18F-sodium fluoride positron emission tomography/computed tomography (PET/CT), yet their respective pain phenotypes differed significantly. Over 4 weeks, the average pain reported by Patient A was 0.4/0-10 scale. Patient B reported average pain of 7.8/0-10 scale distributed across the entire skull and left facial region. Patient B did not experience pain relief from analgesics or more aggressive treatments (denosumab). In both patients, evaluation of trigeminal nerve divisions (V1, V2, and V3) with CT and magnetic resonance imaging (MRI) revealed nerve compression and displacement with more involvement of the left trigeminal branches relative to the right. First-time employment of diffusion MRI and tractography suggested reduced apparent fiber density within the cisternal segment of the trigeminal nerve, particularly for Patient B and in the left hemisphere. These cases highlight heterogeneous clinical presentation and neurobiological properties in craniofacial FD and also, the disconnect between peripheral pathology and pain severity. We hypothesize that a detailed phenotypic characterization of patients that incorporates an advanced imaging approach probing the trigeminal system may provide enhanced insights into the variable experiences with pain in craniofacial FD.

RESUMO

Patients diagnosed with McCune-Albright Syndrome (MAS) frequently manifest craniofacial fibrous dysplasia (FD). Craniofacial FD can impinge nerve fibers causing visual loss as well as craniofacial pain. Surgical decompression of affected nerves is performed, with variable efficacy, in an attempt to restore function or alleviate symptoms. Here, we present a case of a 12-year-old MAS patient with visual deficits, particularly in the left eye (confirmed by enlarged blind spots on Goldmann visual field testing), and craniofacial pain. Decompression surgery of the left optic nerve mildly improved vision, while persistent visual deficits were noted at a 3-month follow-up assessment. An in-depth, imaging-based evaluation of the visual system, including the retinal nerve fiber layer, optic nerves, and central nervous system (CNS) visual pathways, revealed multiple abnormalities throughout the visual processing stream. In the current FD/MAS patient, a loss of white matter fiber density within the left optic radiation and functional changes involving the left primary visual cortex were observed. Aberrant structural and functional abnormalities embedded within central visual pathways may play a role in facilitating deficits in vision in FD/MAS and contribute to the variable outcome following peripheral nerve decompression surgery.

RESUMO

This study aims to enhance understanding of mother-daughter communication about dating and romantic relationships. We explored how Mexican-origin, mostly immigrant mothers talked about these topics with their daughters (ages 13 to 16 years) using videotaped observational methods. Themes drawn from the maternal messages contained in the conversations of 132 mother-daughter dyads show that mothers promote positive decision-making among their daughters, advising them to take their time, choose partners wisely, insist on respect from boys, maintain autonomy in relationships, pursue education goals, and develop a sense of self-worth. Mothers expressed concern about their daughters being pressured or manipulated into having unwanted sex, which led to messages about negative partner dynamics predominating in conversations. Communication about risks, however, included only implicit advice about self-protective behaviours and few messages about the potential for dating violence and abuse. We discuss the implications for improving the design of sexual health communication programmes in which mothers and daughters jointly participate.

RESUMO

Introducción: La odinofonía se define como el dolor durante la fonación. Se trata de una molestia frecuente en los profesionales de la voz. Se ha estimado que quienes la sufren presentarían mayor sensibilidad perilaríngea; sin embargo, esta situación no ha sido del todo evidenciada. Objetivo: Comparar los umbrales de presión de los tejidos perilaríngeos entre pacientes con odinofonía e individuos asintomáticos. Material y método: Se incluyó a un total de 42 mujeres profesionales de la voz o estudiantes de carreras afines. De este total, se formaron 2grupos, el primero (G1) estuvo compuesto por 21 individuos asintomáticos (sin dolor durante la fonación), cuya edad era de 21.5±1.94 años. Mientras que el segundo (G2), con una edad promedio de 25.1±2.27 años, incluyó a 21 sujetos que presentaban dolor durante la fonación. A ambos grupos se los evaluó, mediante algometría, los umbrales de presión de los tejidos perilaríngeos. Resultado: Los umbrales de presión de las personas que sufren de odinofonía fluctuaron entre 300 a 2,000 g, mientras que en los individuos asintomáticos se encontraron entre 1,000 a 2,700 g. Conclusión: Los umbrales de presión perilaríngeos son significativamente más bajos en aquellos pacientes que sufren de odinofonía en comparación con quienes son asintomáticos.(AU)


Introduction: Odynophonia is defined as pain during phonation. Referring to frequent discomfort that professionals of the voice experience. It is estimated that those who suffer this symptom will present high perilaryngeal sensitivity; however, this situation has not been proved. Objective: The main objective of this investigation is to compare the perilaryngeal tissue pressure thresholds between patients with odynophonia and asymptomatic individuals. Material and method: A total of 42 female voice professionals and students with related careers were included. From this total, 2groups were extracted, the first (G1) was composed of 21 asymptomatic individuals (without pain during phonation), aged 21.5±1.94 years. Meanwhile, the second group (G2) comprised 21 subjects who presented pain during phonation with a mean age of 25.1±2.27 years. The perilaryngeal tissue pressure thresholds of both groups were evaluated through algometry. Results: The pressure threshold in those suffering from odynophonia fluctuated between 300 and 2,000 grams, while that of asymptomatic individuals were between 1,000 to 2,700 grams. Conclusion: Perilaryngeal tissue pressure thresholds were significantly lower in the patients suffering odynophonia in comparison with those who were asymptomatic.(AU)

RESUMO

A mandated shelter-in-place and other restrictions associated with the coronavirus disease pandemic precipitated a decline in tuberculosis diagnoses in San Francisco, California, USA. Several months into the pandemic, severe illness resulting in hospitalization or death increased compared with prepandemic levels, warranting heightened vigilance for tuberculosis in at-risk populations.

RESUMO

Resumen Introducción:: El índice leucoglucémico es un factor pronóstico, poco conocido y utilizado, que relaciona la glucemia y los leucocitos registrados al ingreso hospitalario. Su importancia radica en la determinación del riesgo de complicaciones y la mortalidad en pacientes con infarto agudo de miocardio. Objetivo: Establecer al índice leucoglucémico como factor predictor de complicaciones durante la evolución intrahospitalaria en los pacientes con infarto agudo de miocardio. Método: Estudio de tipo epidemiológico, analítico, observacional y de corte transversal, en una cohorte de pacientes que ingresaron con infarto agudo de miocardio durante un período de un año y tres meses. Resultados: Se incluyó en el estudio a 205 pacientes con infarto agudo de miocardio, cuyo promedio de edad fue de 62.99 ± 12.2 años, con predominio en varones con 69.3%. El infarto agudo de miocardio con elevación del segmento ST predominó en frecuencia con 63.9% y mayor tasa de complicaciones (p < 0.001). El promedio del índice leucoglucémico fue de 1,578.41 ± 1,208.1 y el punto de corte establecido fue de 656.8, de acuerdo con la curva ROC, con sensibilidad del 95.8% y especificidad del 73% para la predicción de complicaciones intrahospitalarias, con OR de 7.89. Conclusión: Un índice leucoglucémico > 656.8 representa un riesgo de 7.89 veces de desarrollar complicaciones en la población estudiada.


Abstract Introduction: Leukoglycemic index is a poorly known and used prognostic factor that correlates blood glucose and leukocytes which are taken at hospital admission. Its importance lies in determining complications and mortality risks in patients with acute myocardial infarction. Objective: To establish the leukoglycemic index as a predictor of complications during the in-hospital evolution in patients with acute myocardial infarction. Methods: Epidemiological, observational, cross-sectional, crosssectional study on a cohort of patients admitted with acute myocardial infarction during a period of 1 year 3 months. Results: 205 patients with acute myocardial infarction were included in this study. The mean age was 62.99 ± 12.2 years old, more frequently in males by 69.3%. It was determined that acute myocardial infarction with ST elevation predominated both in frequency with 63.9%, as well as with a higher rate of complications (p < 0.001). The average of leukoglycemic index was 1578.41 ± 1208.1 and the cut-off point was 656.8, according to ROC curve, with sensitivity of 95.8% and specificity of 73% for the prediction of inhospital complications, OR 7.89. Conclusions: A leukoglycemic index greater than 656.8 represents a 7.89-fold risk of developing complications in the study population.

RESUMO

Little is known about the nature of normative mother-daughter everyday disagreements in Mexican family contexts in which daughters are socialized to avoid conflict out of respect and deference to authority. Observations of videotaped conversations of 130 Mexican-origin mothers and their adolescent (13- to 16-year-old) daughters discussing their disagreements were systematically coded. Analyses of the conversations showed that the most frequently recurring conflicts involved autonomy privileges (appearance, friendships, going out, media use), household responsibilities (chores, sibling caretaking), and family dynamics (sibling tensions, sibling differential treatment, mutual respect in communication). Daughters from traditional immigrant families who had lived longer in Mexico were just as assertive in expressing their viewpoints as daughters from less traditional families, although they were less likely to display negative affect.

RESUMO

Objectives. To assess costs of video and traditional in-person directly observed therapy (DOT) for tuberculosis (TB) treatment to health departments and patients in New York City, Rhode Island, and San Francisco, California.Methods. We collected health department costs for video DOT (VDOT; live and recorded), and in-person DOT (field- and clinic-based). Time-motion surveys estimated provider time and cost. A separate survey collected patient costs. We used a regression model to estimate cost by DOT type.Results. Between August 2017 and June 2018, 343 DOT sessions were captured from 225 patients; 87 completed a survey. Patient costs were lowest for VDOT live ($1.01) and highest for clinic DOT ($34.53). The societal (health department + patient) costs of VDOT live and recorded ($6.65 and $12.64, respectively) were less than field and clinic DOT ($21.40 and $46.11, respectively). VDOT recorded health department cost was not statistically different from field DOT cost in Rhode Island.Conclusions. Among the 4 different modalities, both types of VDOT were associated with lower societal costs when compared with traditional forms of DOT.Public Health Implications. VDOT was associated with lower costs from the societal perspective and may reduce public health costs when TB incidence is high.

RESUMO

CONTEXT: Adjuvant radiation therapy has been recommended for patients at higher risk of relapse from renal cell carcinoma (RCC) to improve disease-free survival (DFS) and overall survival (OS) after radical nephrectomy. OBJECTIVE: To quantify the benefit of adjuvant radiation therapy. EVIDENCE ACQUISITION: A systematic review of electronic databases identified publications exploring the association between adjuvant radiation therapy and locoregional recurrence (LRR), DFS, and OS among patients after radical nephrectomy for early-stage RCC. Hazard ratios for DFS were weighted and pooled using the generic inverse variance and random effects model. Odds ratios for LRR, DFS, and OS at 5yr were weighted and pooled in a meta-analysis using Mantel-Haenszel random-effects modeling. EVIDENCE SYNTHESIS: Twelve studies comprising 1624 patients were included in the analysis. Ten studies were retrospective and two were randomized controlled trials. Adjuvant radiation therapy was delivered to 37% of patients. The median follow-up was 49mo. Adjuvant radiation therapy was not associated with better DFS or OS at 5yr, but was associated with less LRR. CONCLUSIONS: With the caveat that confounding by indication may result from pooling data from predominantly nonrandomized studies, adjuvant radiation after radical nephrectomy was not associated with improved DFS or OS but was associated with less LRR. PATIENT SUMMARY: Radiation therapy after resection of renal cell carcinoma with a high risk of relapse may reduce the risk of local recurrence but not the risk of disease recurrence or death after 5yr.

RESUMO

CONTEXT: Five checkpoint inhibitors have been approved as 1st line (cisplatin-ineligible) or 2nd line therapies for patients with metastatic urothelial carcinoma of the bladder. As only about 30% of patients respond, the need for a biomarker for patient selection exists. OBJECTIVE: To determine if PD-L1 expression is a prognostic factor of objective response rate (ORR) and overall survival (OS) in patients with urothelial carcinoma being treated with checkpoint inhibitors. EVIDENCE ACQUISITION: A search of PubMed and major conference proceedings identified trials of PD-L1 inhibitors as first- or second-line therapies for metastatic bladder cancer. Odds ratios (OR) for ORR and OS compared PD-L1 positive and PD-L1 negative patients. Data were weighted and pooled in a meta-analysis, and subgroup analyses compared PD-L1 status cut-offs. EVIDENCE SYNTHESIS: Ten studies comprising 2755 patients were identified, of which 2030 patients (74%) received immune checkpoint inhibitors. Eight studies were eligible for ORR analysis (1530 patients) and five studies for OS (829 patients). PD-L1 patients had a significantly higher ORR than PD-L1 negative patients (1.82, 95%CI 1.18-2.77; p = 0.007). Weighted mean OS was 11.5 months (range 8.7-15.9 months). PD-L1 status was not prognostic for 12 month OS (OR = 0.81, 95%CI 0.47-1.40; p = 0.45). CONCLUSION: In patients treated with PD-L1 inhibitors for metastatic urothelial carcinoma, PD-L1 status is prognostic for ORR but not OS. Our findings warrant additional investigation. PATIENT SUMMARY: Five immunotherapy drugs are approved for bladder cancer therapy. PD-L1 expression predicts higher ORR but not OS. More data is needed to identify the patient population most benefitted by immunotherapy.

RESUMO

OBJECTIVE: Mature B-cell non-Hodgkin lymphoma (B-NHL) comprises more than 50% of all non-Hodgkin lymphoma (NHL) in children and adolescents. An official report published by the Mexican National Center for the Control and Prevention of Cancer in the Pediatric and Adolescent Populations, reported a lymphoma OS of 71% (including all Hodgkin and NHL). The Mexican Association of Pediatric Oncology and Hematology conducted a retrospective study to analyze the clinical characteristics and outcomes of children with diagnosis of B-NHL in Mexico, in order to perceive the main areas of improvement in the health care. METHODS: From 1 January 2000 to 31 December 2016, 166 pediatric patients were diagnosed with B-cell NHL at the participant institutions. RESULTS: According to histology the outcomes were 5-year EFS 63%, for BL/BLL, and 80% DLBCL, (P = .051), 5-year PFS 81%, for BL/BLL, and 91% for DLBCL, (P = .126), and 5-year OS 71%, for BL/BLL, and 83% for DLBCL, (P = .095). DISCUSSION: Overall, 18 patients died due to acute treatment toxicity, resulting in a cumulative incidence of toxic death of 10.84% and an early death rate of 7.23%, defined as <30 days after initial treatment. In conclusion, there is an urgent need to establish an academic collaboration to create strategies to improve pediatric cancer care according to our resources, especially in diseases with expected excellent prognosis as B-NHL. These strategies must include comprehensive supportive care, early referral, and the creation of easy communication between pediatric and adults centers as well as late-effects clinics.

RESUMO

Purpose Limited data describe the delivery of pediatric cancer care in Mexico. We report a nationwide survey of pediatric cancer units. Methods An electronic survey was distributed to 74 pediatric cancer units in Mexico to describe case volumes; organization of care; and availability of medical/surgical specialists, supportive care, complex therapies, and diagnostic services. Centers were classified as low (< 30 new patients/year), medium (30 to 59/year) and high (≥ 60/year). Results Sixty-two centers completed the survey (response rate, 84%). The median annual new case volume per center was 50 (interquartile range [IQR], 23 to 81). Thirty-four percent (n = 21), 26% (n = 16), and 40% (n = 25) of units were low-, medium-, and high-volume centers, respectively. Treatment units reported a median of two pediatric oncologists (IQR, 2) and one pediatric hematologist (IQR, 1 to 2). Availability of medical and surgical subspecialists varied by center size, with substantially more specialist support at higher-volume centers ( P < .01). Multidisciplinary tumor boards are available at 29% (six of 21), 56% (nine of 16), and 76% (19 of 25) of low- to high-volume centers, respectively ( P = .005). Radiation and palliative care services are available at 42% (n = 26) and 63% (n = 36) of all centers, which did not vary by center volume. Educational support for hospitalized children and school reintegration programs are available at 56% (n = 36) and 58% (n = 36) of centers, respectively. One third (38% [n = 23]) of centers reported that at least one half of patients were lost to follow-up during the transition from pediatric to adult programs. Conclusion A large variation exists in annual case volumes across Mexican pediatric cancer centers. Additional efforts to increase access to multidisciplinary, supportive, and palliative care across all pediatric cancer units in Mexico are required.

RESUMO

BACKGROUND: The epidermal growth factor receptor (EGFR) is a member of the ErbB family of membrane tyrosine-kinase receptors. Studies exploring the prognostic role of EGFR-overexpression in early breast cancer have shown variable results, and the true prognostic value of EGFR is unknown. METHODS: A systematic review of identified publications exploring the association between EGFR-overexpression (as defined from different techniques and cut-offs) and outcomes [disease-free (DFS) and, overall survival (OS)] in women with early breast cancer. The hazard ratios (HR) for DFS and OS were weighted and pooled in a meta-analysis using generic inverse variance and random effects modeling. RESULTS: Fifty-three studies comprising 21,418 women were included. EGFR-overexpression was found in 27% of the patients. Primary analysis included studies reporting HRs from multivariable analyses (10 studies including 4857 patients with HRs for OS and 17 studies comprising 8747 patients with HRs for DFS), EGFR-overexpression was associated with worse OS (HR 1.98, 95% CI: 1.59-2.47, p < .001) and DFS (HR 1.59, 95% CI 1.30-1.95, p < .001). The influence of EGFR overexpression on DFS was greater in women with triple negative tumors compared to women with non-triple negative tumors (HR 2.35 versus HR 1.45, respectively; p = .01). Analysis looking at odd ratios for both 5-year and 10-year for DFS and OS showed similar results. CONCLUSION: EGFR-overexpression appears to be associated with reduced OS and DFS in women with early breast cancer. Patients with triple negative and EGFR-overexpression have poorer OS and DFS than those with triple negative tumors and normal EGFR expression.

RESUMO

BACKGROUND: Ki-67 for quantifying tumor proliferation is widely used. In localized prostate cancer (PCa), despite a suggested predictive role of Ki-67 for outcomes after therapies, it has not been incorporated into clinical practice. Herein, we conduct a systematic review and meta-analysis of the literature reporting the association of Ki-67 and disease outcomes in PCa treated radically. METHODS: Medline and EMBASE databases were searched without date or language restrictions, using "KI67" and "prostate cancer" MeSH terms. Studies reporting Ki-67 association with clinical outcomes (disease-free survival [DFS], biochemical failure-free survival, rate of distant metastases [DM], disease-specific survival [DSS], or overall survival [OS], or all of these) in patients with PCa managed actively were included, and relevant data extracted by 2 independent reviewers. Odds ratios (OR) were weighted and pooled in a meta-analysis using Mantel-Haenszel random-effect modeling. RESULTS: Twenty-one studies comprising 5,419 patients met eligibility for analysis, and 67.6% of patients had low Ki-67. Mean Ki-67 was 6.14%. High Ki-67 was strongly associated with worse clinical outcomes. DFS was better in those patients with low Ki-67 at 5 and 10 years (OR = 0.32, 95% CI: 0.23-0.44, P<0.00001; OR = 0.31, 95% CI: 0.20-0.48, P<0.00001). Similarly, low Ki-67 was related to improved DSS at 5 and 10 years (OR = 0.15, 95% CI: 0.10-0.21, P<0.00001; OR = 0.16, 95% CI: 0.06-0.40, P<0.00001). Association between low Ki-67 scores with improved OS (OR = 0.47; 95% CI: 0.37-0.61; P<0.00001) and high Ki-67 scores with DM at 5 years (OR = 4.07; 95% CI: 2.52-6.58; P<0.00001) was consistently observed. CONCLUSIONS: High Ki-67 expression in localized PCa is a factor of poor prognosis for DSS, biochemical failure-free survival, DFS, DM, and OS after curative-intent treatments. Incorporation into clinical routine of this widely available and standardized biomarker should be strongly considered.

RESUMO

Ganglioneuromas are rare, benign neoplasms derived from sympathetic neural crest progenitor cells. In the pediatric population, ganglioneuromas usually develop in the mediastinum or retroperitoneum. We report the case of a 3-year-old boy who presented with a painless enlarging neck mass, which was found to be a parapharyngeal space ganglioneuroma that extended to the skull base. We summarize the current principles regarding the diagnostic workup and treatment of these neoplasms, and we briefly review the literature.

RESUMO

BACKGROUND AIMS: Cerebral palsy (CP) is related to severe perinatal hypoxia with permanent brain damage in nearly 50% of surviving preterm infants. Cell therapy is a potential therapeutic option for CP by several mechanisms, including immunomodulation through cytokine and growth factor secretion. METHODS: In this phase I open-label clinical trial, 18 pediatric patients with CP were included to assess the safety of autologous bone marrow-derived total nucleated cell (TNC) intrathecal and intravenous injection after stimulation with granulocyte colony-stimulating factor. Motor, cognitive, communication, personal-social and adaptive areas were evaluated at baseline and 1 and 6 months after the procedure through the use of the Battelle Developmental Inventory. Magnetic resonance imaging was performed at baseline and 6 months after therapy. This study was registered in ClinicaTrials.gov (NCT01019733). RESULTS: A median of 13.12 × 10(8) TNCs (range, 4.83-53.87) including 10.02 × 10(6) CD34+ cells (range, 1.02-29.9) in a volume of 7 mL (range, 4-10.5) was infused intrathecally. The remaining cells from the bone marrow aspirate were administered intravenously; 6.01 × 10(8) TNCs (range, 1.36-17.85), with 3.39 × 10(6) cells being CD34+. Early adverse effects included headache, vomiting, fever and stiff neck occurred in three patients. No serious complications were documented. An overall 4.7-month increase in developmental age according to the Battelle Developmental Inventory, including all areas of evaluation, was observed (±SD 2.63). No MRI changes at 6 months of follow-up were found. CONCLUSIONS: Subarachnoid placement of autologous bone marrow-derived TNC in children with CP is a safe procedure. The results suggest a possible increase in neurological function.
